Abstract
The present disclosure provides methods and devices for transmitting and receiving a pilot signal, so as to reduce the number of antenna ports for transmitting the pilot signal and reduce pilot resource consumption. The method for transmitting the pilot signal includes: generating, by a base station, a pilot signal formed by a wide beam and a pilot signal formed by a plurality of narrow beams; and transmitting, by the base station, the pilot signals to a UE through at least one pre-configured first antenna port and at least one pre-configured second antenna port, the pilot signal formed by the wide beam being transmitted through the first antenna port, and the pilot signal formed by the plurality of narrow beams being transmitted through the second antenna port.

A method for transmitting a pilot signal, comprising:
- generating, by a base station, a pilot signal formed by a wide beam and a pilot signal formed by a plurality of narrow beams;
- and
- transmitting, by the base station, the pilot signals to a User Equipment (UE) through at least one pre-configured first antenna port and at least one pre-configured second antenna port, the pilot signal formed by the wide beam being transmitted through the first antenna port, and the pilot signal formed by the plurality of narrow beams being transmitted through the second antenna port.
3-4. (canceled)
A method for receiving a pilot signal, comprising:
- receiving, by a User Equipment (UE), pilot signals from a base station, the pilot signals comprising a pilot signal formed by a wide beam and transmitted by the base station through first antenna ports and a pilot signal formed by a plurality of narrow beams and transmitted by the base station through second antenna ports;
- and
- measuring, by the UE, the received pilot signals to determine an optimal first antenna port and an optimal second antenna port.
14-15. (canceled)
A device for transmitting a pilot signal, comprising:
- a processing unit configured to generate a pilot signal formed by a wide beam and a pilot signal formed by a plurality of narrow beams;
- and
- a transmission unit connected to the processing unit and configured to transmit the pilot signals to a User Equipment (UE) through at least one pre-configured first antenna port and at least one pre-configured second antenna port, the pilot signal formed by the wide beam being transmitted through the first antenna port, and the pilot signal formed by the plurality of narrow beams being transmitted through the second antenna port.
21-22. (canceled)
A device for receiving a pilot signal, comprising:
- a reception unit configured to receive pilot signals from a base station, the pilot signals comprising a pilot signal formed by a wide beam and transmitted by the base station through first antenna ports and a pilot signal formed by a plurality of narrow beams and transmitted by the base station through second antenna ports;
- and
- a processing unit connected to the reception unit and configured to measure the received pilot signals to determine an optimal first antenna port and an optimal second antenna port.
